R. P. STECKEL LIQUID DELIVERY LINE Filed y 29. 1950 Hudailpiz]? saga/m anew/up Patented Dec. 29, 1931 UNETED STATES PATENT OFFICE LIQUID DELIVERY LINE Application filed May 29,

The invention relates to a flexible-ended liquid delivery line in which a horizontally swin able pipe is connected with a stationary part of the line and in which a horizontally and vertically swingable terminal pipe is connected with the free end of said horizontally swingable pipe, allowing the free end of said terminal pipe to be shifted horizontally over any of a great number of points and also allowing it to be vertically moved. The invention is designed primarily for use over ranges and the like used for cooking purpose in the kitchens of hotels, restaurants, etc, for the purpose of delivering water to any of a number of cooking utensils upon the range orthe like. It is customary to provide only a stationary spigot near the range and to move the receptacles under said spigot for total or partial filling, and again from said spigot after such filling, and these operations entail quite an amount of work which is eliminated by the use of the invention.

It is the principal object of the invention to provide a novel arrangement of pipes and swivel couplings therefor, whereby the two movable pipes may be horizontally swung to va "ions positions and whereby the terminal or delivery pipe may be vertically swung regardless of the position to which it has been horizontally moved. 2

Another object is to provide a construction which. permits quick, easy and compact folding of the movable pipes into an out-ofthe-way position when their use is not required.

A still further aim is to provide for the discharge of a small quantity of water from the flexible end of the water delivery line into a kettle or the like should this be re quired in cooking, for instance, when it is necessary to maintain the water level in the receptacle at predetermined height or when a small quantity of water must be added to a receptacle while stirring the contents thereof. The small quantity of water is supplied through a valved by-pass around a conventional spigot and it allows more convenient and accurate relation of the water than 1930. Serial No. 157,403-

can be obtained by endeavoring to effect a H minute adjustment of said spigot.

iVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a perspective view showing the invention installed over a range. 1

Fig. 2 is a perspective view showing the con-trivance partially folded.-

Fig. 3 is a horizontal sectional view more clearly showing the valved by-pass around the valve of the spigot.

In the drawings above briefly described, the numeral 5 denotes a stationary pipe line portion having a spigot 6 above the top T of a range. A vertical-axis swivel coupling 7 is connected at one end with the spigot 6, and an elbow 8 is connected with the other end of said coupling, said elbow extending horizontally and being connected with a horizontal pipe 9, the latter being horizontally swing-able about the vertical axis of the coupling 7. A second elbow 10 is connected with the free end of the pipe 9 and extends vertically from the latter, being connected with one end of a second vertical-axis swivel coupling 11. A third elbow 12 is connected with the end of the coupling 11 remote from the elbow 10 and extends horizontally. This elbow 12 is connected with one end of a horizontal-axis swivel coupling 13 and the end of the latter remote from saic elbow 12, is connected with a fourth elbow 14. The elbow 14- is connected with a delivery or terminal pipe 15 preferably having a downturned elbow 16 at its front end;

The pipe 9 is horizontally swingable about the vertical axis of the swivel coupling 7; the pipe 15 is horizontally swingable about the vertical axis of the swivel coupling 11, and said pipe 15 is vertically swingable about the horizontal axis of the swivel coupling 13, regardless of the horizontal position to which said pipe 15 may be swungi. Hence, the flexible end of the pipe line afforded by the invention, allows quick and easy positioning of the delivery end of the pipe 15 over any required point, as well as allowing verthat the invention is not restricted to use in connection with ranges or the like but ma be employed wherever applicable. vVhen it is used to supply water for cooking purposes however, the detail now to be described, is of particular advantage.

Around the valve of the spigot 5, I provide a small by-pass 17 having a needle valve 18. With the spigot valve closed, it will be seen that the valve 18 may be opened to any required extent, allowing a small amount of water to discharge from the pipe 15. This will often be of advantage in cooking and the stream of water may be more easily and finely regulated than by attemptingto make a minute adjustment of the spigot. This feature of the invention may also be of advantage in other uses of the contrivance.

From the foregoing, it will be seen that I have provided a very simple and inexpensive, yet a highly desirable arrangement of pipes and oints for attaining the desired end. Particular attention is invited to the fact that the pipe 15 may be vertically swung regardless of the position which it may assume either before or after swinging about the vertical axis of the coupling 11. Even should the pipes 9 and 15 occupy positions in which they are substantially unidirectional, as in Figs. 1 and 2, the pipe 15 may be readily swung vertically and either of said pipes may be horizontally swung. Moreover, when the use of the contrivance is not needed, the pipes 9 and 15 may be positioned about as shown in Fig. 2 and then bodily swung back to or near right angular relation with the pipe 5, in which folded position, they will be entirely out of the way.

In a somewhat analogous arrangement of pipes and joints with which I am familiar, while a vertically and horizontally swingable terminal pipe is provided, corresponding to the pipe 15 above described, said terminal pipe cannot be vertically swung unless it be first swung laterally from a pipe which corresponds with the pipe 9 above described. Hence, the prior structure to which I refer is not well adapted to uses for which the present invention is designed, and it cannot be as conveniently manipulated to discharge the water at the required point or elevation.

I claim 1. In a liquid delivery line, a stationary pipe, a horizontally swingable pipe, a vertical-axis swivel coupling connecting said horizontally swingable pipe with said stationary pipe, a second vertical-axis swivel coupling connected with and communicating with the free end of said horizontally swingable pipe, a horizontal-axis swivel coupling connected at one end with and communicating with the end of said second vertical-axis swivel coupling most remote from said horizontally swingable pipe, and a third pipe connected with and communicating with the end of said horizontal-axis coupling most remote from said second vertical-axis coupling, said third pipe being vertically swingable about the axis of said horizontal-axis coupling regardless of the position to which said third pipe be horizontally swung about the axis of said second vertical-axis coupling.

2. In a liquid delivery line, a stationary pipe, a vertical-axis swivel coupling connected at one end with the delivery end of said stationary pipe, an elbow connected with the other end of said coupling and directed horizontally therefrom, a horizontal pipe connected with said elbow and swingable horizontally about the vertical axis of said coupling, a second elbow connected with the free end of said horizontal pipe and directed vertically therefrom, a second vertical-axis swivel coupling connected with said second ibow, a third elbow connected with said second swivel coupling and directed horizontally therefrom, a horizontal-axis swivel coupling connected with said third elbow, a fourth elbow connected with said horizontalaxis swivel coupling, and a delivery pipe connected with said fourth elbow, said delivery pipe being horizontally swingable about the axis of said second vertical-axis coupling, said delivery pipe being also vertically swingable about the axis of said horizontalaxis coupling regardless of the position to which said delivery pipe be horizontally swung.

3. In a liquid delivery line embodying a spigot having the conventional valved flow passage, and a flexible line end extending from the outlet end of said spigot; a valved by-pass around the valve of said spigot, both ends of said by-pass being in communication with said flow passage, whereby a small stream of water may be conducted to said flexible line end when the spigot valve is closed.

In testimony whereof I atfix my signature.
